DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an adhesive, a coating,
The present invention relates to a fibrous resin used as a material, a molding material, a binder ( a binder), and the like , and a structure using the same.

[0002]

BACKGROUND OF THE INVENTION Generally, an adhesive is applied to an adhesive surface, an adhesive is applied to a flat surface, or a binder such as cement or asphalt is used as an aggregate. Liquid resins are used for mixing with other solid substances to form a mixture to construct an appropriately shaped structure.

However, the use conditions of the above liquid resin are restricted by its fluidity. In other words, when the liquid resin is applied or put on thickly, especially when applied to a vertical wall using a brush, a spatula, or a spray gun, the liquid resin is applied until it solidifies. There is a problem that a dripping phenomenon that moves downward due to its own weight occurs, and not only is the coated surface not uniformly finished, but also solidification cannot be completely performed.

Therefore, it is necessary to apply the liquid resin on the application surface in a thickness that does not allow the liquid resin to drip and solidify the resin, and to repeat the same operation on the application surface several times to obtain the desired thickness.

[0005] When used as a binder (binder) such as cement or asphalt, a liquid resin is mixed with another solid material to form a mixture, which is used as a material of a suitably shaped structure. Even when the mixture is put into a mold or the like to form a block or structure, or a structure such as a road surface or a civil engineering structure, the liquid is not allowed to solidify until the liquid resin coated on the object is solidified. Figure 1
As shown in FIGS. 1 (a) and 1 (b), only the liquid resin 2 sinks downward through the gap between the solids 1, and significant liquid unevenness occurs at the upper and lower parts of the structure. It may not be uniform and sufficient strength may not be expected. Therefore, there is a problem that only a material having a thickness of about 1.5 to 2 times the particle diameter of the solid matter to be mixed can be produced.

Therefore, in order to reduce the dripping phenomenon,
There have been proposals to increase the viscosity by adding thickeners and additives to the liquid resin.However, if the viscosity is increased more than necessary, workability will deteriorate and the use of the liquid resin more than necessary will result. However, it is impossible to completely eliminate the dripping phenomenon of the liquid resin in the region of the appropriate viscosity.

[0007] A method has also been proposed in which rock wool (rock wool) is mixed with a liquid resin, and a thickener is further added to increase the viscosity. Become That is,
Rock wool is made by melting rock with high heat and cooling it. It is processed into a fibrous shape with a thickness of about 7 microns and a length of about 20 millimeters, and has a cotton-like shape. This single thread-like substance is an aggregate made of fine rocks, and easily becomes powdery by a small external pressure, and cannot maintain the form as a fiber. Moreover, the rock wool material itself does not have the property of absorbing or impregnating the liquid resin, but merely has the resin adhered to the surface of the powdered rock wool, and merely has a thickening effect. It is merely an attempt to increase the viscosity. In addition, since the powdered rock wool causes moisture in the air to adhere to the surface, it becomes a negative factor to the properties of the resin itself as a thickener for the liquid resin, and is not always suitable.

That is, as long as the liquid resin is in the liquid region, it is impossible to eliminate the dripping phenomenon. If the viscosity is increased until the dripping phenomenon does not occur, the solid resin is consequently formed. Some curing phenomena begin due to the viscosity and volatility inherently possessed by the resin itself, causing internal curing and greatly affecting the performance and characteristics of the resin itself. Therefore, there is a problem that it is not easy to apply such a liquid resin or to mix it with another solid material to form a mixture, and even if it is made, it will not be proper.

In view of the above, the present invention can select a viscosity suitable for use without deteriorating the inherent properties of a liquid resin, and furthermore, a fibrous resin which does not cause dripping and a fibrous resin molded from the fibrous resin. The purpose is to obtain a structured structure.

[0010]

According to a first aspect of the present invention, a liquid is provided on a surface.
50mm thick with body resin adhered and coated until saturated

Consisting of a liquid in which the aggregate of the fibers covers the surface of each fiber.

[0011] In the second invention, at least the surface is provided with a liquid.
50mm thick with body resin adhered and coated until saturated
An assembly of fibers less than cron and less than 20 mm in length
Consisting of a liquid in which the aggregate of the fibers covers the surface of each fiber.
Due to the adhesiveness of the body resin, the fibers randomly overlap each other,
Fibers that are kneaded and kneaded together in a paste
And resin, and aggregate consisting of solid fine particle size were mixed and kneaded, a structure that a mixture of the kneaded state characterized by being molded and solidified into a predetermined shape.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

A fiber 10 such as a natural fiber or a chemical fiber processed to a thickness of 50 μm or less and a length of 20 mm or less is heated to a temperature several degrees higher than the temperature of the liquid resin 11 and immersed in the liquid resin 11. If it is hygroscopic or water-absorbent, it is impregnated into the fiber until it is saturated. Next, a sufficient amount of liquid resin to sufficiently coat the fiber surface is further supplied until it becomes saturated. For fibers having no hygroscopicity or water absorption, that is, fibers having no factor that penetrates into the interior of the fiber, a sufficient amount of liquid resin for sufficiently covering the surface of the fiber is supplied until the fiber is saturated.

A large amount of the fibers saturated with the liquid resin in this way is collected, and the fibers are slowly mixed to knead into a paste-like new substance as shown in FIGS. 1 (a) and 1 (b). In this state, due to the viscosity of the liquid resin 11 on which the fiber 10 and the fiber 10 cover the surface, the fiber 10 overlaps or continues in a row, or overlaps in tandem,
Alternatively, it is an aggregate of fibers that are connected and randomly entangled with each other, and as a result, are coated with the liquid resin in a paste state, and the fiberized resin 12 is formed by this aggregate.

The viscosity of the liquid resin is usually in the range of 1 to 50 poise. However, as described above, the liquid resin is supplied to the fibers until they are saturated, and the fibers are mixed and kneaded.
It can be changed from 000 poise to a resin having a viscosity of 400,000 poise. That is, one fiber 1
Each book is covered with a liquid resin in the form of a thick film,
Furthermore, the high viscosity can be obtained by the fibers being intricately entangled with each other.

Usually, there is a difference depending on the viscosity of the liquid resin and the physical properties of the fiber, but the fiber is 0.0% for 1 W% of the liquid resin.
When the liquid resin is saturated at 5 W% to 0.5 W%, the liquid resin alone does not precipitate when the liquid resin adheres to the fiber in a saturated state.

By the way, when a liquid resin is immersed in a fiber and mixed to make it saturated, simply mixing the liquid resin with the fiber does not necessarily result in proper integration by coating the fiber with the liquid resin. The adhesive strength is affected by the situation of the coated liquid resin, and an appropriate adhesive strength cannot be expected. In some cases, after solidification, the fiber and the resin may be separated from each other within the adhesive structure.

Therefore, in the present invention, as described above, when a liquid resin is immersed in a fiber and mixed to make the fiber into a saturated state, the temperature of the fiber is 1 ° C. or higher than the temperature of the liquid resin, Heated inside. Therefore, the volume of the fiber is increased by thermal expansion due to the above-mentioned heating, and at the same time, the surface area increases. The film thickness is increased, thereby increasing the adhesive strength of the finished fiberized resin, and the fiber's liquid resin adsorptivity is sufficiently enhanced.

As described above, in the present invention, the fibrous resin becomes the same as that in the state where the liquid portion is removed, and even when the resin is applied to a vertically placed wall surface, it can be applied by the same operation method as that of the liquid resin. Since there is no dripping phenomenon, the thickness of the coating can be adjusted according to the purpose of use. In addition, the surface finish and the strength and various properties of the coated body are uniform, and the properties of the resin can be sufficiently brought out.

Further, if the fiberized resin according to the present invention,
There is no sinking phenomenon (drip phenomenon) caused by the resin, and furthermore, the characteristics of the resin itself are not impaired. Furthermore, when a volume structure is made with this fiberized resin, the fiberized resin hits the line uniformly in any part of the entire volume structure, and the adhesive strength, bonding condition, and various characteristics are inherent to the resin. Can be used as it is. Further, in the conventional liquid resin, since the physical properties of the resin itself constitute a liquid by an aggregate of liquid particles, the gap between the solids remains as a space or the liquid resin However, when the fibrous resin according to the present invention is used, the solid is mixed with the solid while the surface of the solid is covered with the fibrous resin, and the mixture is molded. Since the solid is finally fixed and set by vibration or compaction, the solid is rubbed with the solid during the previous working process, so that the solid is coated on the solid. As shown in FIGS. 2 (a) and 2 (b)
As shown in the figure, the gap between the solid 13 and the solid 13 is formed by a fiber-like resin filter in a mesh state, where fibers are stuck together in a spider's web due to a part of the fiberized resin 12 coated on the solid. Is made randomly and three-dimensionally. Then, in this state, the volume structure is solidified by a curing method that matches the characteristics and workability of each resin,
The structure can be completed while maintaining its shape.

The adhesive strength of the structure solidified by this method exhibits the strength of the fibrous resin itself, hardly dissolves the contained components after solidification, and the fibrous resin exhibits the properties of the liquid resin. Since it is taken over without any loss, there is no need to take any special consideration in the current selection of liquid resin materials that can be selected in various ways depending on the purpose of use.

In addition, even when compared with the reinforced plastics currently used in the industry, the reinforced plastics are solidified by sandwiching a cloth-like material woven of glass fiber in the liquid resin, thereby solidifying the liquid resin. Although it has succeeded in producing high strength that could not be obtained by solidification strength alone, its manufacturing process requires a high degree of molding technology.

In the case of a fibrous resin, the fibers are saturated with a liquid resin, and the fibrous resin already has the same performance as a reinforced plastic.

Like the liquid resin, the fibrous resin can be solidified by any means such as solidifying means, two-part by a hardener, thermoplastic by heating, or oxidizing by reacting with moisture in the air. There is no need to take any special measures, and the method of use can be variously selected.

Examples of the fibrous resin according to the present invention and those using the fibrous resin as an adhesive, a coating material, a molding material and a binder will be described below.

Example 1 A glass fiber having a thickness of 7 μm or less and a length of 8 mm or less was selected from fibers having no hygroscopicity or water absorbency, and heated to 40 ° C. with respect to 1 W% of a liquid resin having a viscosity of 45 poise. 0.05 W% of the heated glass fiber was sufficiently immersed in the liquid resin one-fifth at a time, and stirred while slowly breaking the glass fiber with a stirrer.

While supplying the liquid resin in one-fifth increments until the fibers become saturated, the mixture was slowly mixed and the stirring operation was repeated, and the mixture was stirred until the liquid of the liquid resin became invisible. .

The finished fibrous resin is 1200000
It was an assembly of soft paste-like fibers having a poise viscosity, and no problems were observed during use.

Also, natural fibers such as cotton and silk, and chemical fibers such as glass, carbon, aluminum, and ceramics are used as the fibers.
In contrast, the fibers became saturated in the range of 0.01 W% to 0.2 W%.

Further, 0.1 W% of the heated fiber is soaked and mixed with 1 W% of the liquid resin having an extremely low viscosity and 1 W% so that the temperature becomes 20 ° C. higher than that of the liquid resin, and the mixture is slowly stirred. For the fiberized resin in the saturated state,
By adding 0.01 W% to 0.05 W% of a thickener and adjusting the viscosity, 50,000 poise to 400,000
The viscosity could be adjusted within the poise range. In each case, the state of the fiberized resin was visually observed, and it was confirmed that the fiberized resin was completed. Example 2 50 g of 45 ° C. glass fiber (processed to a thickness of 7 μm and a length of 3 mm) was put into a container and sufficiently loosened. Further, 500 g of an epoxy-based liquid synthetic resin at 20 ° C. was added, and the mixture was slowly mixed and kneaded. While adding 500 g of the epoxy-based liquid synthetic resin at a time, it was confirmed that a saturated state was reached at a total amount of 1500 g, and the fiberized resin was completed.

Next, a curing agent for solidifying the finished fiberized resin is added at a weight ratio of 50 W% to the total amount of the epoxy-based liquid synthetic resin, and further kneaded to obtain a fiberized resin adhesive. As shown, the wooden board 14 is 300 mm long, 300 mm wide, and 10 mm thick.
Is applied with a spatula and a brush to a thickness of about 0.2 mm on one side of the surface, and the surface is processed into a cube having a side of 50 mm, such as wood, rubber, metal, cement concrete, etc. Wooden board 14 with one surface of a block-shaped solid material made of each material as an adhesive surface and an adhesive applied thereto
And bonded on one side.

After the solidification, a load was applied to the tip of the surface to be bonded of each block to test the bonding strength. However, no peeling of the bonding surface was observed and the piece of wood was broken.

Also, as shown in FIG.
A fiberized resin adhesive 12 is applied at a thickness of about 0.2 mm to one surface of a block-shaped solid material 15 formed into a cube having a side of 50 mm such as metal, cement concrete, etc. An attempt was made to bond with a different material, but it was found that the bond strength was sufficient to withstand normal use.

As a result, it was confirmed that the fibrous resin obtained by saturating the glass fiber with the epoxy liquid synthetic resin had sufficient performance as an adhesive. Example 3 50 g of a carbon fiber heated to 50 ° C. (processed to a thickness of 5 μm and processed to a length of 5 mm) was put into a container and sufficiently loosened.
Kneading was repeated while adding 500 g each of the polyester-based liquid synthetic resin while slowly mixing and kneading, and a total amount of 1700 g was confirmed to be a saturated state, thereby completing the fibrous resin.

Next, in order to solidify the finished fibrous resin, a curing agent was added at a weight ratio of 3 w% to the polyester-based liquid synthetic resin, kneaded, and used as a molding material.

The polyester fiberized resin 12 completed in a metal mold 16 as shown in FIGS. 5 (a) and 5 (b).
And a sealable container 17 (internal volume 200 ml, wall thickness 10 mm) as shown in FIG.
8 was molded and solidified to be completed.

Further, PCB (97%) was put in a sealed container of the completed polyester fiberized resin and sealed, and an elution test was carried out. As a result, there was no elution of the components, and complete sealing was possible. Further, it was also confirmed that the strength of the container itself was higher than that of a molded article made of a usual liquid synthetic resin because the container contained fibers.

As a result, a fibrous resin obtained by saturating a carbon fiber with a polyester-based liquid synthetic resin can be used as a molding material. In addition, it has the same strength as a reinforced plastic and can also contain a PCB. Was confirmed.

EXAMPLE 4 A vinyl ester-based liquid synthesis at 15 ° C. was performed while 50 g of a fiber of 60 ° C. obtained by processing 50 mm each of a natural fiber, broth and silk, in an amount of 50% each to a length of 5 mm, while stirring. The resin was added in an amount of 500 grams, and the kneading was repeated while the vinyl ester-based liquid synthetic resin was further added in an amount of 500 grams each while slowly mixing and kneading, and it was confirmed that the resin was saturated in a total amount of 2,000 grams, thereby completing the fibrous resin. . Further, in order to adjust the viscosity, a total of 10 g of a thickener was added in two portions and kneaded, and the vinyl ester-based fiberized resin was adjusted to a viscosity which facilitates the work. Next, a hardening agent for solidifying the completed fiberized resin was added and kneaded, and used as a coating material.

As shown in FIG. 7, a cracked cement concrete flat plate 19 is set upright, and the space between the cracked portions is filled with the vinyl ester fiberized resin 12 using a spatula. The whole surface was applied with a thickness of about 3 mm.

In this operation, the effect of filling the cracked portion, the effect of adhesion, the presence or absence of the liquid dripping phenomenon at the time of application, and the workability were confirmed. Both effects and workability were very good. No dripping was observed. After solidification, the adhesive strength and surface strength of the cracked portion and the coated surface were sufficient, and no leakage from the cracked portion was observed.

As a result, a fibrous resin obtained by saturating a vinyl ester-based liquid synthetic resin with natural fibers can be used as a coating material, and furthermore, there is no dripping phenomenon and the work is performed by adjusting the viscosity. It was confirmed that the nature was good.

Example 5 Glass fiber 50 7 microns thick and 3 millimeters long
% And 6% length of glass fiber 50% are mixed together, and 23 kg is processed by stirring thoroughly, heated to 35 ° C. and put into a kneading stirrer, and a polyester liquid synthetic resin at 15 ° C. 477 kiloram was added while kneading with a stirrer, and after about 5 minutes, a saturated state was confirmed and the fibrous resin was completed. Further, 1 kg of a thickener was added to complete about 500 kg of a polyester fiberized resin having a viscosity of 150,000 poise. Using this fiberized resin as a binder, various solids were used as aggregates to produce a volume structure.

Aggregates include gravel (particle size 2 to 8 mm), crushed stone (particle size 2 to 20 mm), river sand, waste materials (plastic, glass, shells, rubber, metal slag, wood chips, rice hulls, china, cement And asphalt concrete) processed to a particle size of 3 to 10 mm, and the like.

A flat plate block 20 having a length of 300 millimeters and a width of 300 millimeters and a thickness of 30 millimeters as shown in FIG. 8 was manufactured using the above-mentioned various aggregates.

First, the aggregate is put into a mixer used for kneading cement concrete, mortar and the like (one type), and 4 w% to 10 w% based on the weight of the put aggregate.
Then, w% of the fiberized resin was added, and the mixture was stirred and kneaded with a mixer to prepare a mixture of the aggregate and the fiberized resin. After stirring for about 5 minutes, it was confirmed that the fibrous resin 12 coated the surface of the aggregate 21 in a thick film form. Next, a hardening agent for solidifying the fiberized resin was added to the mixture at a weight ratio of 3% by weight based on the used fiberized resin, and kneaded.

While putting the completed aggregate mixture into the mold of the flat plate block, light vibration was applied to the entire mold, and the surface was pressed down with a gold trowel to finish the mold. It was confirmed that the flat block-shaped volume structure completed after solidification was removed from the mold and bonded to another solid product with a polyester fiberized resin binder to complete the volume structure.

As a result, the fibrous resin is the most suitable binder (binder) for using a wide variety of solids as an aggregate, and has no special characteristic in workability. It was also found that the strength and various characteristics of the completed structure were very excellent.

EXAMPLE 6 23 kg of a very short glass fiber heated to 45 ° C. and having a thickness of 7 μm and a length of 0.3 mm was put into a kneading agitator, and a polyester liquid synthetic resin at 15 ° C. 477 kg of a mixture obtained by previously mixing 430 kg of the urethane-based liquid synthetic resin and 47 kg of the urethane-based liquid synthetic resin was charged and kneaded slowly with a stirrer. After about 5 minutes, the saturated state was confirmed, and the fibrous resin was completed. In this state, it was confirmed that a short glass fiber of 0.3 mm was connected by the viscosity of the coated resin and a thread was drawn like a long fiber. Next, 5 kg of a thickener was added to increase the viscosity to 200,000 poise, and adjusted to a viscosity suitable for use. Using this polyester urethane fiberized resin as a binder, a pavement surface pavement was made using gravel and crushed stone as aggregate, and pavement pavement was performed.

The aggregate is gravel (particle diameter 3 to 8 mm)
And crushed stone (particle size: 3 to 15 mm) were used.

First, a roadbed with a width of 5 meters and an extension of 10 meters is prepared, and the length is divided into two sections of 5 meters each, and two types of foundation roadbed materials are used. In this example, the asphalt concrete layer 23 was formed to have a thickness of 50 mm, and a surface pavement material having a thickness of 30 mm and using a fiberized resin binder was applied to the upper surface of the foundation roadbed.

Next, 2 cubic meters of gravel 24 (about 3.4 tons)
Was put into a large mixer truck for ready-mixed concrete, and about 204 kg of a fiberized resin binder 12 of 6% by weight of gravel 24 was added, and the mixer was rotated and kneaded for 10 minutes. Since it was confirmed that the surface of the gravel was covered with the fibrous resin in a thick film form, 4 kg of a curing agent was further added and kneaded for 1 minute to complete a surface pavement material.

Next, the completed pavement material was taken out of the mixer truck, dropped directly onto the road surface, spread with a rake, rolled while applying vibration with a compactor, and finally finished with a metal trowel.

As shown in FIG. 9, the completed surface subgrade had no resin dripping at all, had appropriate voids, and had a uniform cross-sectional structure.

Next, 2 crushed rice of crushed stone 25 (about 3.3 tons)
Using a large mixer truck, surface pavement was completed in the same manner as in the case of gravel. The road surface was leveled by using a finisher (rolling machine with roadbed material) used for asphalt pavement. The finisher drops the paving material from the mixer truck, and the finisher is a machine that has the function of leveling the road while running on its own, and furthermore, it has a function to hold down the road surface while applying vibration, so the work by human power has been greatly reduced. .

As shown in FIG. 10, the completed roadbed had no dripping of the resin, had appropriate gaps, and had a uniform cross-sectional structure.

As a result, in addition to the fact that the fiberized resin can be used as it is for the civil engineering and construction machinery and tools generally used at present, there is no special use and work method, and the workability is extremely good. The completed surface layer roadbed was also an excellent structure, and it was confirmed that the fiberized resin was a sufficient material as a binder.

[0058]

As described above, the fiberized resin of the present invention is coated as described above until the surface of the fiber is saturated, and the fibers are complicatedly entangled with each other due to the viscosity of the resin on the coated surface. A new substance was formed, and the dripping phenomenon could be eliminated. In addition, a variety of fibers and a wide variety of resins can be combined to create fiberized resins with new and superior properties. Now you can do it. In addition, fiberized resin has the same or higher strength characteristics as reinforced plastic because resin and fiber are already integrated, and depending on how it is used as fiberized resin, various new characteristics can be created. It is possible.

When fiberized resin is used as an adhesive,
Because there is no dripping phenomenon, even when removing from the container,
Also in the work such as laying and pouring, the adhesive does not stain the surroundings due to the dripping flow, and does not cause uneven coating. As a result, the waste of the adhesive is reduced and the adhesive strength is improved.

When the fibrous resin is used as a coating material or a protective film material, since there is no dripping phenomenon, in addition to the above-mentioned characteristics, it is necessary to uniformly apply a desired coating film thickness in a single operation. Can be. Moreover, both the adhesive strength and the coating strength are very excellent.

When a fiberized resin is used as a molding material,
In addition to the above-mentioned features, since the fibrous resin already contains fibers, strength equal to or higher than that of the reinforced plastic can be obtained, and therefore, it is not necessary to sandwich the glass fiber cloth during the molding process. . Therefore, simplification of the molding operation can be expected, and a product having extremely excellent molded product strength can be obtained.

When the fibrous resin is used as a binder (binder), there is no dripping phenomenon. In addition to the above-described features, a solid material is mixed with the fibrous resin as an aggregate to form a fibrous resin mixture. Any volume-shaped structure can be constructed by using as a material.

In this case, since there is no dripping, any part of the structure becomes uniform and clean, and the bonding strength between the aggregates is equal to or higher than that of the reinforced plastic. rare. In addition, the voids between the aggregates are also solidified in a spider web shape with the fibrous resin, so that the shape can be maintained for a long time. In addition, since the solids are mixed, the surface of the solids is coated with a fibrous resin in a thick film form, so that the components contained in the solids hardly elute. Therefore, as long as the industrial waste is processed to a particle size of 30 mm or less as a solid, any waste can be reused as aggregate (solid). Further, since the structure according to the present invention has a porosity of 30% to 18%, it has a low unit volume weight, is excellent in sound absorption effect and water permeability effect, has good air permeability, and has an effect of preventing surface temperature from rising due to heat. .
